2,892,075 HOUSING FOR 'SIGNALING APPARATUS Max (2. Nelson, Lakewood,Ohio, asslgnor, by mesne assignments, to the United States of America asrepresented by the Secretary of the Navy Application November '29, 1957,Serial N0. 699,375 4 Claims. (Cl. 240-412) tomary in the naval serviceto assign the upkeep of such signaling appanatus to a signalman who isrequired to check and clean the equipment daily "in order to insureproper operation of the apparatus. In such prior signaling apparatus,the tranformers and other ment, which is auxiliary to; the lamp andshutter assembly is usually not housed therewith and consequentlysubstantial floor area is required for the entire signaling apparatusassembly. Additionally, unless properly protected the delicate operatingelements of the signaling apparatus, such as the lens and reflector, maybe 'delteriously affected by salt spray which in time not only reducesthe operating efliciency of the apparatus but often requires replacementof parts.

Accordingly, it is the broad object of this invention to provide asingle unitary protective housing for the signal transmitting assemblyand its auxiliary power transmitting equipment.

Another object is to provide a single unitary protective housing forsignal or searchlights and its auxiliary equipment which is strong andcompact, and yet is arranged to provide ready access to its parts forinspection, repair, or replacement.

Other and further objects of the invention will be more readilyunderstood from the following description taken in connection with thedrawings, wherein:

Fig. l is a side elevational view of the housing with a portion of itsshell removed to show details; and

Fig. 2 is a rear elevational view of the housing; and

Fig. 3 is a view taken along the line 33 of Fig. 1; and

Fig. 4 is a housing; and

Fig. 5 shows a detail of the apparatus.

Referring to Figure 1 the housing is indicated generally at and consistsof a lower power transmitting compartment 11, a central signalingcompartment 12 and a protective cover compartment 13. The housing isformed by bottom pan 14 which is supported at floor level by means of atransverse channel and angle iron indicated at 15 and 16 respectively.An outer shell 17 has its lower edge portion secured preferably, asshown, to the outer wall of the pan 14 and has its upper edgeterminating about midway of the housing. The shell 17 is not a completecylinder but as shown in Figure 4 is slotted at its rear face andfurther arranged to provide vertical edge portions 18 between which arereceived risers 19-19.

The risers"19-19, as shown in Fig. I, extend vertically of bothcompartments 11 and 12 and, as shown clearly in Fig. 4, have innerportions which are positioned perspective view of the lower portion ofthe power supply equip- .20 signal is an incandescent or carbon arclamp. It is cusshelves function to receive the shelves 31 shown in Figs.

within the shell '17. The inner portions are bent outwardly at 20 andhave the'ir oute'r edges-in contact with the inner wall of shell 17 toform vertical spaces '21 which may be provided with verticalstrengthening ribs '22 as shown. The risers '19 are preferably securedto the shell 17 by welding or bolting the vertical-edge portions '18 ofthe shell thereto to' pr'ovide a rigid structure. in effect, the risersprovide a hon-like chamber which has an open outer end embraced "by arectangular frame formed by vertical angle irons 23 23 and upper andlower angle irons 24 and 25 which are apertured' as shown to permitremovable securernent of 'the'hous ing to a wall and permit access tothe box-like chamber as desired. V v

The box-like chamber provided by the-risers 19--- 19' is provided withplurality o'fihorizontal shelves '26 and 27, shown in Fig. 4 whichareisec'ured *to therisers i 19 toextend horizontally inwardly of theshell 1'7and havetheir inner ends supported by vertical posts 28- 28.These transformers, reactors, condensors, etc., indicated 'by dashedlines in Fig. 2= and which are used in transmitting'power to the lampwhich is also supported between the risers 19*but disposed above andwithin the signaling compartment as will now 'be described. v

The signaling compartment 1 2 is formedimmediately above theequipment'comp'artment 1 1 by means of similar upper and lower generallydish-shaped partitions 30am! l and 3 and indetail in Figl 5 "which arearranged to receive and clamp'therebehveen an ou'ter window indicated atand *a lensindicated at The lower partition 31 is inverted to complementthe upper partition 30 and both are developed or cut from metalspinnings. As shown in Fig. 5, each partition 30 and 31 is provided withan irregular cutout section which is defined by an inner verticalU-shaped flange 35 and an outer slotted portion defined by lines 3636with similar intermediate triangular shaped open areas which are definedgenerally by lines 37 and 38 and which merge into narrow slots 39.

The cutout sections of the partitions 30 and 31 permit their beingreceived by the inner end portions 20 of the risers 19 as shown in Fig.4 while the solid area of the partitions permit the window 32 and lens33 to be held therebetween. To this end each partition is formed asshown in Fig. 1 with an outer annular vertical flange or step 40 forreceiving the window 32 and an inner annular vertical flange or step 41for receiving the lens 33. The window is maintained in place by a lowerannular band 42 and a flange 43 of a bafile element in the cover sectionwhich will be described later. The lens 33 is maintained in place byupper and lower bands 44-44.

The window 32 is preferably formed of arcuate segments of substantially220 and may have a wire mesh (not shown) disposed therebetween.Similarly, the lens is formed of arcuate segments of substantially 220so that a large sector of the signal compartment of the housing is opento provide for omnidirectional signaling. To effect this signaling, asignal lamp 50 is disposed within the central compartment 12 and hasvertical posts 51 which are supported at the front ends of upper andlower U-shaped arms 52-52 which have their rear ends connected to acarrier bar 53 as shown in Fig. 3. The carrier bar 53 is notched at54-54 as shown in Fig. 2 to be slidable on horizontal ribs 55-55 whichare mounted at the upper end portions of the risers 19-19. Thisarrangement permits the lamp 50 to be readily inserted into compartment12 or removed therefrom by access through the open rear end of thehousing. Arcuate plates 56 close compartment 12.

The cover compartment of the housing is arranged to permit thedissipation of gases or air formed within the I) z i, L

fliousingi'while preventing the entry of water spray. To

this end the cover shaped baflle indicated generally at 60, having anannular depending flange 43 heretofore referred to and disposed ..aboutthe step 4010f the upper clamping element 30 and which is provided witha central opening 61. An outer dome 62 is'spaced fromthe bafiie 60 by anannular screen 63 and the dome 62 provides an annular opening 64 withthe flange 43 of .baffle 60 permitting passage of air or .gases from thehousing compartments to the exterior of the housing. A drain pan 65 may,as shown, be dis- ;posed below the opening 61 by means of hangers 66which are secured to the dome 62. The vertical spaces 21 ;shown in Fig.4 are in communication at their upper ends ;withthe upper compartment 13and function to dissipate heat'formed in compartments 11 and 12.

While there has been described a preferred embodiment of the invention,it will be obvious to those skilled ;i nthe.ar t thatvarious changes andmodifications may be made therein within the scope of the invention,which .is to be limited only by the appended claims.
